lTo (4t/.Z 'wh/0711, t may concern:

Beit known that we, CLARENCE C. SIBLEY, residing in Perth Amboy,Middlesex county,` New Jersey, and GEORGE A.- LUTZ, residing in New Yorkcity, boroughl of Brooklyn, New York, citizens of the United States,have in` 'vented certain new and useful Improvements in Conduits forElectric Wires, of which the following is a specification.

Our invention relates to improvements in the class of conduits havingone side open to permit access to the contained wires and a removablecover thereon; and the object of the invention is to provide improvedmeans for detachably holding the cover upon the conduit, also, providingmeans to prevent a tool from engaging the contained wires or and theconduit.

The invention comprises a conduit having one sido open and provided atthe edges with havingits edges laid upon said flanges or cover andhaving in-` portions gripping said cover upon the conduit, and bypreference the cover is depressed in a loi'igitudim'tl direction betweenits edges, whereby such depressed portion of the cover enters theconduit to .prevent the entrance of a tool into the conduit between theflanges or ribs on the conduit and the edges of the cover.

`Reference is to be had to the acconilmnying drawings, forming part.l1ereof, wherein-- Figure l is a perspective view, partly broken, of' aconduit embodying our invention; and Fig. 2 is a similar view showing amodification.

'ln thc afcoinpanying drawings, in which similar numerals of referenceindicate corresponding parts in the views, the conduit 1 has alongitudinal channel with oneside open, and by' preference wo form theconduit from a sheet or strip of suitable metal by bending the same intosubstantially rectangular form, providingr a bottom l, sides lbwardly-bi-nt end vand when the cli l, and flanges or ribs ld at theedges of the side walls extending longitudiiuilly of the i projectingoutwardly beyond from theoside Walls at'substantially right anv glesthereto. 2 indicates a cover laced over the open side of the conduitandp having its outer edges 21L laid upon the flanges or ribs l", and at3 are clips extendin transversely across and upon the cover am? havintheir ends at 3a bent around and under the anges or ribs l, said clipsholding the cover firmly upon the conduit, whereby said` cli s may bereadily removed when the cover 1s to be detached from the conduit. Theclios may be formed as shown in Fig. 1, and when applied or detachedtheir bent spring-like ends may be sprung over the ribs lfi, as theouter edges of said ribs are rounded.

ln the form shown in Fig. 2 one end of the clip may be made' in curvedform, as 3, and the other end left straight or partially bent, isapplied over the cover its curved end w1 l first en age a rib 1d, andthen the straight or parta ly-bent end may be bent under the rib ld.

By preference the cover 2 is depressed centrally, as at 2b, formingwalls or shoulders 2 between thc Side edge/s2a and the central portion,whereby if a tool, nail, or the like is pushed between the iianges ld ofthe conduit and the edges 2'L of the cover the tool or the like will beprevented by the wall 2clfroin engagin, rthe contained wire orinsulation thereon. Y

As shown in Fig. l, the cli s 3 are bent centrally to correspond to thesliape of the cover 2, so that the clip will fit firmly and snugly uponsuch cover, the bent portions 31 of the clips corresponding to the planeof the walls 2"', whereby the clips are prevented from beingr readilytorn away from the conduit.

' For sonic use, however, the clips 3 need'not be bent centrally,butinay across the cover, as in Fig. 2.

Having now described'our invention, what we claim is-M 1.. A conduithaving oi'itwardly-extending extend straight Enc* sfLQ zmgcs, mid clipsm their ends Lo amor 11110.
